24FC04H-E/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24FC04H-E/ST is a 4Kbit I2C EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates at 1 MHz with a 450 ns access time and supports a wide supply voltage range of 1.7V to 5.5V. The component is housed in an 8-TSSOP surface mount package and maintains active product status with full RoHS3 compliance. Substitute parts are identified when electrical specifications, memory organization, interface protocols, and physical packaging remain identical across manufacturing variants.

Substitute Part Grouping Explanation

The 24FC04H-E/ST and 24FC04-E/ST are parametric equivalents within the Microchip 24FC04 base product family. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Memory capacity and organization (4Kbit, 256 x 8 x 2 configuration)
• I2C serial interface protocol at 1 MHz operation
• Electrical performance metrics (450 ns access time, 5 ms write cycle)
• Supply voltage compatibility (1.7V to 5.5V range)
• Operating temperature range (-40°C to 125°C)
• Physical package specification (8-TSSOP with identical dimensions)
• Compliance certifications (RoHS3, REACH Unaffected, MSL 1)

Both parts maintain identical functional and electrical characteristics, differing only in manufacturing date code or internal revision designations indicated by the suffix variation (H-E versus -E).

Parameter Comparison

Engineering Selection Recommendations

Both the 24FC04H-E/ST and 24FC04-E/ST are suitable for direct substitution in applications requiring 4Kbit I2C EEPROM functionality. Selection between these parts may be based on inventory availability and lead time considerations. The 24FC04-E/ST currently maintains higher stock levels (1143 pcs) compared to the 24FC04H-E/ST (818 pcs). Both parts carry identical compliance certifications including RoHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring equivalent reliability and regulatory acceptance in production environments.

Frequently Asked Questions (FAQ)

Q: Can 24FC04-E/ST replace 24FC04H-E/ST in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, memory organization, I2C interface characteristics, and 8-TSSOP packaging. No design modifications are required.

Q: Are there differences in pin configuration between these parts?

A: No. Both parts use the same 8-TSSOP package with identical pin assignments and functionality.

Q: Do these parts have different temperature operating ranges?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C.

Q: What is the significance of the "H" designation in 24FC04H-E/ST?

A: The "H" suffix indicates an internal manufacturing revision or date code variant within the Microchip 24FC04 product line. This does not affect electrical performance or functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 24FC04H-E/ST and 24FC04-E/ST are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions (8-TSSOP, 0.173" width, 4.40mm) and pin configurations allow direct substitution without PCB layout modifications.
